Hi I have the burning every so often, but my main concern is every time I stand it feels as though my left knee is breaking into. It takes me a moment or two before I can walk. Has anyone else experienced this. I had surgery twice on this knee. the 1st time was Jan 8th, I then has an MUA on Feb. 27th because knee wouldn't been. I then had the 2nd surgery on May 21st 2019. The Dr. went in and put a smaller spacer and removed scar tissue. Dr. said I had so much scar tissue that it was unbelievable he said he had never seen anything like it out of the 10 + years that he has been doing surgery. I was doing pretty good until about 2 1/2 weeks ago I started having this excruciating pain on the outside of my knee. My therapist was concerned and she texted my surgeon telling him that he need to see me because something wasn't right. Can anyone elaborate on this matter?
